Abstract:
The farmer field study was carried out during 2016-17 at village Saida, Takhatpur Tehsil in Bilaspur district of Chhattisgarh to evaluate the “Long term effects of rice establishment methods on chemical properties and rice productivity in vertisols of Chhattisgarh plain”. The trial was laid out in Randomized block design with twelve replication and three treatments. Rice based cropping system in Vertisols. The soil of experiment fields was clay in texture having slightly acidic to slightly alkaline pH, low in nitrogen, medium phosphorus and potassium medium to high. The available iron, manganese, zinc and copper content of the experimental field were sufficient. The study on the long term effect of rice establishment methods on soil chemical properties and crop productivity were evaluated after harvest of rice crop. In this study, three rice establishment methods i.e. transplanting, broadcast-biasi and direct seeded line sowing were laid in main treatment. A study was undertaken to describe the soil resources of the investigation field. The residual effect of rice establishment methods on soil chemical properties like the available nitrogen, phosphorus, potassium and sulphur content were significantly higher in surface layer (0-20 cm) with transplanting method over other treatments however sub surface layer (20-40 cm) was non-significantly increases with transplanting method but also obtained nutrient content decreases in than surface layer. Micro nutrient content in surface layer (0-20 cm) higher than sub surface layer and non-significantly increases with transplanting method.
